Route 301 northbound and southbound are reduced to a single lane between Roseland Drive and Barnsfield Road for bridge construction and realignment of the roadway. A northbound and southbound lane remain open in this area. 

Roseland Road/Route 301 Intersection Realignment 

Starting July 21, 2022, Roseland Road has been realigned at the intersection with Route 301 to allow crews to improve Route 301 leading up to the opening of the new Nice/Middleton Bridge. 

Weather permitting, this new intersection configuration is estimated to be completed in summer 2022.
